None of them have any legs. Im a sucker for baby feet and would have liked to see them. Nice lighting on the first, the next 3 have slight, but weird shadows and not the best pose. The BW version of this is a little flat. The last one is blown out, but it did make me laugh because it looks like hes singing opera Cute baby though, is he/she yours??

The baby in the first one and the B&W versions are very unnatural.
Obviously the baby is not standing but there is nothing the background to suggest otherwise giving it an unnatural appearance.
Like it could be the baby brother of the baby that was floating in space in 2001!

The kid kinda looks like she is in pain in each of the shots. The cutoff seems a little weird, particularly with the look of pain... the first one honestly looked like something you'd see in a medical record log of some kind...

The last one is my favorite out of the series. As mentioned before the poses seem a bit unnatural. In the last the lighting, color (half way between sepia and B&W almost), and eye sharpness I really like. A different pose would've been nicer, though.

this is a good place to start from...even though people arent loving these shots, there is alot to learn. I think the pp work is a little clinical too...over-contrasted? Eyes should sharp but babies should look softer. Also with poses...infants should look soft and comfy. I think the baby looks uncomfortable.

but really, this is good to get this feedback, it really helps to get better to hear these things
